IMPROVED BRICK-MACHINE.

The Schedule referred to n these Letters Patent and making part of thesame.

To all whom 'it may concern.:

Beit known that I, JOHN McMANUs, ol' Pittsburg, in the county ofAllegheny, und Stute oi" Pennsylvanio, have invented n new and usefulImprovement in Brick-Machines; and I do hereby declare that thei'ollowing is a. full, clear, und exact description thereof, referencebeing had to the accompanying drawings, and to the letterszind iiguresof reference marked thereon.

The nature of my invention consists in the Arrangement of amixing-hopper;y n jointed, endless apron, for carrying the moulds underthe hopper to be iilled,2u1d from under it, to be borne olf fordelivering the brick from the moulds; and an endless belt for carryingbuck.

the empty moulds, to be again pluced on the jointed und endless apron,to be again carried under the hopper, for the purpose ofbeing lled.

To enable Others skilled in the nrt to make und use my invention, I willproceed to describe its construeu tion and operation.

In the accompanying drawings, which form part of my specification-Figure 1, Sheet A, is a side elevation of my improvement inbrick-machines.

Figure 2, Sheet A, is u top View or plan ofthe some.

Figure 3, Sheet B, is a. longitudinal section, whenA cut through at linefm.

In the drnwings- A represents the fiume of the machine.

B' represents the hopper for mixing the clay.

The hopper is provided with n vertical shaft, u, from which project aseries of mixing-turns, s

On the upper end of this shaft is placed n Wheel, u, into which gears aWheel, l placed on n shaft, 3, which is supported on pedestal w.

The shafts marked l, 2, 3, endet are provided with pulleys for the beltsmarked e, j, g, and h.

The jointed und endless a-prou A is provided with cogs, or teeth, x,which mesh into the teeth, or cogs, of the section of u wheel, R, placedon the shaft 1.

The jointed und endless apron A is also provided With carrying-picces,or strips, x, which :ire arranged at righta-ngles to the longitudinalplane of the apron A, and at a suitable dista-nce apart, for carryingthe moulds t directly under the opening o, in the bottom of the hopperB.

The apron A travels over a. series of friction-rollers, 5, as shownin'lig. 3

Forward of the hopper B', and directly over the apron A, and justsuioicntly above the apron to allow the moulds t to pass under, isarranged e cut-oli, c,

which is set et un oblique tingle to the longitudinal plane of tho npronA, shown in lig. 2.

rlhe endless apron D travels over pulley 8, und rollers o und 9, undmot-ion is imported tothe pron through the medium ol'helt f, :md pulleyon the shaft 2, und is used for carrying otl' the moulds from the npronA.

The moulds t are deposited in the chamber Ji ui'ter the moulds have beenbornoofl', und the moulded brick hnve'been delivered from them.

As the skillful mechanic will readily understand the construction undnrrnngementoi' thc several pants of my improvement in brick-machines,und the relation that suid parts bear to ouch other, from the foregoingdescription, und by reference to the accompanying drawings, I willthin-clore proceed to describe their operntlon, which is as follows:

Motion is imparted to the shaft l by applyingr power to the crunk p.Then clay, which han; been properly moistened with water, is thrown intothe hopper B', where it is mixed by the `urns s.

The revolving ofthe shaft 1 ufillca-nse the belts e, j, g, zuid htotravel in the direction indicated by the arrows shown in ligs. l, 2, ord

The moulds und their bottoni-boards nre placed on the apron A, undcznried under the hopper rI3 by the section cfu wheel, R, which willmore the apron A at intervals, so that the moulds will have time to llduring cnoh stop in thc motion ofthe apron.

The surplus cluy is cut orf the top of the moulds as the;- pass underthe cutter c.

The moulds pass off the ctpron A on to the apron D, and tre carriedalong on it to be borne oli to be delivered.

The empty moulds are then placed onthe belt h, und carried buck into themould-chmuher i. to be again placed on the npron for refilling.

I do not claim the various devices herein shown, for them I know to heseverally old; but luiiving thus described the nurture, construction,und operation of my improvement,

That I clnim :is of my invention, is-

The arrangement ot' the hopper B', endless apron A, wheel Il, cut-off C,endless apron D, belt h, und mould-chamber lz', constructed, arranged,and operating as herein described, luid for the purpose set forth.
